Gender-based violence (GBV) often escalates during humanitarian emergencies, especially when crises result in displacement. Increasingly, displaced persons are living in host communities or informal settlements, with more than half of the world's displaced people living in urban areas. Furthermore, conflict and disasters exacerbate many forms of GBV, such as sexual violence, intimate partner violence (IPV), and early marriage. Often those populations at greatest risk of GBV reside in areas that are difficult to access, both in terms of distance and security. To address these challenges, the International Rescue Committee (IRC), with support from the U.S. State Department, Bureau of Population, Refugees and Migration (BPRM), and European Union Civil Protection and Humanitarian Aid (ECHO), has developed guidelines to support the provision of mobile and remote services to survivors of GBV in out-of-camp humanitarian settings. The guidelines recommend approaches and minimum standards for designing and implementing such approaches to service delivery while adhering to best-practice principles.
